http://bugs.winehq.org/show_bug.cgi?id=59521 --- Comment #4 from Marlon Alex Andrade <marlonalexandrade@gmail.com> --- After analyzing the regression commit c78edbc, I noticed a possible issue for hybrid GPU systems. In visual_from_pixel_format(), when using EGL, the function always returns default_visual regardless of the format: cif (use_egl) { *visual = default_visual; return TRUE; } On hybrid Intel + NVIDIA systems (like the reporter's RTX 4060M + Intel RPL-P, visible in the attached log), default_visual possibly corresponds to the Intel iGPU, while EGL may select the NVIDIA dGPU for rendering. The colormap created with the Intel visual could potentially be incompatible with the NVIDIA EGL surface, which might explain the black window. This could explain why the issue doesn't reproduce on single-GPU systems (tested on AMD RX 6600, X11 and XWayland, Wine 10.16 and 10.17 — no reproduction). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
